It is already 2nd round today and e.g. del Potro-Kohlschreiber is not boring.

Yeah this is the thing I don't understand either.

@Voo: Be happy that the ATP tourneys of IW & Miami always start one day after the WTA ones. If it was the other way round, we wouldn' even have coverage of any 2nd round matches during Miami (and only 16 matches of the 2nd round of IW).
